Beginning with the class of 2023, graduating Pennsylvania high school students will need to demonstrate career or postsecondary preparedness in addition to meeting existing statewide graduation requirements. Act 158 of 2018 outlines five pathways to meeting this requirement, including two that rely exclusively on Keystone Exam performance and three pathways that allow for alternative demonstration of college or career readiness. This significant policy shift likely has implications for all Pennsylvania school districts, including the School District of Philadelphia (SDP). Over the next three years, the Philadelphia Education Research Consortium will be conducting research focused on this policy to understand its implications for SDP. The Philadelphia Education Research Consortium (PERC) is a research partnership between SDP's Office of Research and Evaluation and Research for Action, funded by the William Penn Foundation. In this policy brief, PERC: (1) outlines Act 158 and the new graduation requirements; (2) describes the evolution of the policy; (3) summarizes the previous research conducted on high-stakes graduation requirements in PA; and (4) highlights equity concerns that previous research has raised.
